+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our community a
+harassment-free experience for everyone, regardless of age, body size, visible or
+invisible disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal appearance,
+race, religion, or sexual identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming, diverse,
+inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our community
+include:
+
+- Demonstrating empathy and kindness toward other people
+- Being respectful of differing opinions, viewpoints, and experiences
+- Giving and gracefully accepting constructive feedback
+- Accepting responsibility and apologizing to those affected by our mistakes, and
+  learning from the experience
+- Focusing on what is best not just for us as individuals, but for the overall community
+
+Examples of unacceptable behavior include:
+
+- The use of sexualized language or imagery, and sexual attention or advances of any kind
+- Trolling, insulting or derogatory comments, and personal or political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or email address, without
+  their explicit permission
+- Other conduct which could reasonably be considered inappropriate in a professional
+  setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in response to
+any behavior that they deem inappropriate, threatening, offensive, or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject comments,
+commits, code, wiki edits, issues, and other contributions that are not aligned to this
+Code of Conduct, and will communicate reasons for moderation decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when an
+individual is officially representing the community in public spaces. Examples of
+representing our community include using an official e-mail address, posting via an
+official social media account, or acting as an appointed representative at an online or
+offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported to
+the community leaders responsible for enforcement at mcp-coc@anthropic.com. All
+complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the reporter
+of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining the
+consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing clarity
+around the nature of the violation and an explanation of why the behavior was
+inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No interaction with
+the people involved, including unsolicited interaction with those enforcing the Code of
+Conduct, for a specified period of time. This includes avoiding interactions in community
+spaces as well as external channels like social media. Violating these terms may lead to
+a temporary or permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including sustained
+inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public communication
+with the community for a specified period of time. No public or private interaction with
+the people involved, including unsolicited interaction with those enforcing the Code of
+Conduct, is allowed during this period. Violating these terms may lead to a permanent
+ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community standards,
+including sustained inappropriate behavior, harassment of an individual, or aggression
+toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the
+community.

+# Contributing to Model Context Protocol Java SDK
+
+Thank you for your interest in contributing to the Model Context Protocol Java SDK!
+This document outlines how to contribute to this project.
+
+## Prerequisites
+
+The following software is required to work on the codebase:
+
+- `Java 17` or above
+- `Docker`
+- `npx`
+
+## Getting Started
+
+1. Fork the repository
+2. Clone your fork:
+
+```bash
+git clone https://github.com/YOUR-USERNAME/java-sdk.git
+cd java-sdk
+```
+
+3. Build from source:
+
+```bash
+./mvnw clean install -DskipTests # skip the tests
+./mvnw test # run tests
+```
+
+## Reporting Issues
+
+Please create an issue in the repository if you discover a bug or would like to 
+propose an enhancement. Bug reports should have a reproducer in the form of a code 
+sample or a repository attached that the maintainers or contributors can work with to 
+address the problem.
+
+## Making Changes
+
+1. Create a new branch:
+
+```bash
+git checkout -b feature/your-feature-name
+```
+
+2. Make your changes
+3. Validate your changes:
+
+```bash
+./mvnw clean test
+```
+
+### Change Proposal Guidelines
+
+#### Principles of MCP
+
+1. **Simple + Minimal**: It is much easier to add things to the codebase than it is to
+   remove them. To maintain simplicity, we keep a high bar for adding new concepts and
+   primitives as each addition requires maintenance and compatibility consideration.
+2. **Concrete**: Code changes need to be based on specific usage and implementation
+   challenges and not on speculative ideas. Most importantly, the SDK is meant to 
+   implement the MCP specification.
+
+## Submitting Changes
+
+1. For non-trivial changes, please clarify with the maintainers in an issue whether 
+   you can contribute the change and the desired scope of the change.
+2. For trivial changes (for example a couple of lines or documentation changes) there 
+   is no need to open an issue first.
+3. Push your changes to your fork.
+4. Submit a pull request to the main repository.
+5. Follow the pull request template.
+6. Wait for review.
+7. For any follow-up work, please add new commits instead of force-pushing. This will 
+   allow the reviewer to focus on incremental changes instead of having to restart the 
+   review process.
+
+## Code of Conduct
